THRUST on COLLAR nnnnmc.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filedDecember 18, 1918. Serial No. 267,371.

To all whom it may concern:

Be it known that I, BERNARD RoBnRT Wmormnn, a subject of Britain, residing in West Drayton, England, have invented certain new and useful Imrovements in Thrust or Collar Bearings, of which the following is a specification.

,' The invention relates to thrust or collar bearings of the type described in British s ecification No. 875 of l905 and has for its 0 ject to insure equal distribution of the load over the various pads or blocks and to In the accompanying line 11 of Fig. 2 and Fig. 2 a section on the line 22 of Fig. 1.

The tilting blocks A rest with their white metal surfaces against the thrust collar B.'-

On the back of the blocks A,'circular sprlng disks C are inserted, the centers of the'disks coinciding with the desired tilting points of the blocks. The spring disks C rest against steel balls D, the steel balls being held in position by cages E. The cages E are suitably secured, as for example by bolts, to fixed rings F'through which the thrustis transmitted to the housing Gr. Where the balls rest against the rings F, spring disks 0, are

- inserted, the centers of these disks being opposite the centers of the disks inserted in the blocks. In order to be able to adjust the position of the thrust collar loose rings H are inserted between the rings F and the housing G. The cages E, rings F and ad justing rings H are all made in halves. The blocks A are cast as a ring, the spring disks are inserted and are ground in position before the blocks are separated. In this way complete uniformity of distance between the various blocks is secured and thrust surfaces and the outside of the spring disks is obtained. The spring disks inserted in the rings F are also ground in position so that perfect uniformity of distance between them and the back surface of the ring is obtained. The balls D which form theswivel points are .all way great uniformity of pressure over the the extremely the King of Great of pivot. drawing which fixed ring and metal blocks, shows an example of a construction according to the invention, Figure l is a section on with respect to the fixed ring,

' the of uniform diameter.- In this 1. A thrust-.or collar bearing of the pivoted block type comprising a plurality of metal blocks arranged in a ring around the shaft and abuttingagainst the shaft collar, a fixed ring encircling the shaft and positioned op: posite the ring of metal blocks, a plurality balls interposed between the said and means for maintaimng said balls in definite positions as and for the purpose setrforth.

substantially 2. In athrust or collar bearing ofthe pivoted blocktype as claimed in claim 1, a plurality of spring disks arranged in a circle around the fixed ring and interposed between-said ring and the pivot balls, substantially as and for thepurpose set forth.

3. In a thrust or collar bearing of the pivoted block type as claimed in claim 1, a plurality of spring disks each mounted in one of the pivoted blocksand interposed between said block and a pivot-ball, substantially as .and for the purpose set forth.

4. A thrust or collar bearing of the pivoted block type, comprising on each side of the shaft collar a ring of pivoted blocks bearing against said collar, a fixed ring opposed to the ring-.pf pivoted blocks, a ring of pivot balls equal in number to the pivoted blocks interposed between the said blocks and the fixed ring, and means for maintaining each of the said balls in position to act as a fulcrum for the block opposed to it, substantially as and for the purpose set forth. 5. In a thrust or collar bearing of the pivoted block type as claimed. in claim 4, a spring 'disk ball and block, and a second spring disk-interposed between each pivot ball and the fixed ring, substantially as and for the purpose set forth.'

In testimony whereof I have signed my name to this specification.

BERNARD ROBERT WINGFIELD.
